To all whom it may concern.-

' Be it known that LLnwsoN B. SHELTON, a citizen of the United States,residing at Los Angeles, in the county of Los Angeles and State ofCalifornia, have invented a new'and useful Improvement in Hinges, ofwhich the following is a specification.

The object of my invention is to make a hinge, which when used to mountcasement windows to their frames, will permit the sash thereof, to bepressed down in front of the stool after closing the window, andmyinvention consists of the novel features herein shown, described andclaimed.

The accompanying drawings illustrate my invention, in which,

Figure 1 shows a hinge embodying the principles of my invention.

Fig. 2 shows a surface appearance of the hinge when complete. Fig. 3shows the pivot pin with spiral sprin attached...

Re erringto the, drawings in detail, to describe my 1nventionz- Leaf 1,has the lower jortion of its knuckle ---2v raised away rom the pivot pin--3 sufficiently to make room for aspiral spring 4, to be mountedthereon, and

said raised portion of the knuckle --2--, has the end --5, cutaway toallow it to ass down-over leaf --6, at this point.

he'object of the spiral spring -l-, is to raise the leaf --l-, togetherwith the window sash, when so attached, its upper end so arranged toform a seat for the knuckle of leaf The pivot pin -3-, is'fastened orrigidly placed in the up er knuckle--7- of leaf -6, and may be s otted.or grooved a part of its length to admit the upper end of the spiralspring -4--, and allow it to travel freely therein. The lower end of the'maining portion fastened to a ring the pivot pin --3--,

thus relieve the spiral spring When the hinges are fastened in the usualway to an inner mounted casement window sash and frame, which has, theusual inside stool, the sash may be pressed down in front of the stoolafter closing, when a water tight joint is desired, and fastened.

Having thus described myinvention, what I claim-and desire to secure byLetters Patent of the United States, is

1. In a hinge having the usual alinin knuckles, held together by a pivotpin, 0 one of the knuckles arranged to slide on the pivot pin, at onepoint of its axis and be returned by means of a spiral spring encirclinga'port-ion of the pivot pin between the knuckle ends of the matchedmembers, the

said spiral spring so arranged, that it can be tightened to sustain moreweight.

2. A hinge, one member of which, will slide down on the pivot pin, andthus ermit- LAWSON B. Witnesses E. O. Gunner, H. PEARL GILBERT.
